vessels of the arm + forearm Flashcards
(26 cards)
Name the artery that (at the base of the neck) forms an arch over the cervical pleura behind the anterior scalene muscle
Subclavian artery
Name the 3 parts of the subclavian artery
Medial, posterior + lateral regarding their position to the anterior scalene
The subclavian artery becomes the … artery once it passes the outer border of the … rib
Axillary, first
The axillary artery “ends” in the lower border of a muscle. Which one is it?
Teres major
The axillary artery is divided into 3 portions, based on its position with regards to a muscle. Name the parts + the muscle
Pec minor
Parts: proximal, posterior or distal
The 1. portion of the axillary artery branches into…
The upper thoracic artery
The second portion of the axillary artery branches into…
The thoracoacromial + lateral thoracic arteries
The 3. portion of the axillary a. branches into…
The subscapularis, the posterior + anterior circumflex humeral arteries
The posterior circumflex humeral a. goes to the back alongside with the … nerve, through the … space
Axillary, quadrangular
The anterior circumflex humeral artery surrounds the … part of the … of the humerus
Anterior, surgical neck
Name the medical term for the formation of an arch/connection between vessels (i.e. the anterior + posterior circumflex humeral a.)
Anastomosis
The brachial artery is the continuation of the … artery from the lower border of … (muscle)
Axillary, teres major
Name the artery of the arm that ends in the cubital fossa (anteromedially to the neck of the radius)
Brachial artery
Where in the arm do you place the stethoscope to measure blood pressure? Why?
It’s placed in the anteromedial region of the arm, proximal to the flexion skinfold.
Reason: because of the trajectory of the brachial artery with regards to the humerus (first medial to it, then anterior)
The brachial artery gives branches for the irrigation of … + …
Arm + elbow
Where does the radial artery originate?
In the cubital fossa
Name the muscle that covers the radial artery in its trajectory down the forearm
Brachioradialis
Once the radial artery reaches the wrist, it surrounds a bone (laterally) + enters the palm, forming a structure. Name the bone + the structure
Trapezium, deep palmar arch
Name the artery that originates in the cubital fossa + ends in the radial side of the pisiform
Ulnar artery
Explain the trajectory of the ulnar artery
It runs deep, passing over the brachialis after originating in the fossa. Then it crosses between the 2 heads of the pronator teres + obliquely crosses the FDP.
It meets the ulnar nerve in the middle of the medial side of the forearm + descends to the hand
The superficial palmar arch is formed by the superficial (terminal) branch of an artery of the forearm. Which one is it?
Ulnar artery
Name the vein that’s found in the medial region of the forearm + enters the axilla, forming the axillary vein
Basilic vein
What’s the name of the vein that runs in the lateral region of the arm + forearm + runs through the deltopectoral interval in the shoulder (+ essentially joins the axillary vein)?
Cephalic
Name the 3. vein of the forearm (joins the basilic + cephalic veins in the anterior region of the forearm)
Median (ulnar) vein
